other Embodiment approach

[0068] The electronic component according to the present invention is not limited to the multilayer inductor 10a shown in the above-mentioned embodiment, and design changes may be made within the scope of the main points. Hereinafter, a multilayer inductor 10b according to another embodiment will be described with reference to the drawings. Figure 5 It is an exploded perspective view of the laminated body 11b of the laminated inductor 10b.

[0069] In the multilayer inductor 10a, the number of turns of the coil L is adjusted by adding a new internal conductor 13 between the internal conductor 13f and the internal conductor 13e located on the most negative side in the z-axis direction.

[0070] However, the method of adjusting the number of turns of the coil L is not limited to this. Specifically, the adjustment of the number of turns of the coil L can also be performed by adding a new internal conductor 13 between the internal conductor 13a and the internal conductor 13b located o...

Abstract

An electronic component capable of adjusting the number of turns of a coil without preparing multiple kinds of inner conductors to be positioned at an end of the layer direction is composed of a multilayer body having multiple laminated magnetic layers. A spiral coil includes inner conductors and via-hole conductors connected to each other. Each of the inner conductors has a length of one turn. Both ends of each of the inner conductors are over points A and B. The inner conductor provided at the most negative side in the z-axis direction branches at one end so as to be over the points A and B.

Description

Technical field [0001] The present invention relates to an electronic component, and more specifically, to an electronic component in which a coil is built in a laminate. Background technique [0002] As a conventional electronic component, for example, a multilayer inductor described in Patent Document 1 is known. Figure 7 It is an exploded perspective view of the laminated body 111 of this laminated inductor. [0003] The laminated body 111 includes magnetic layers 112a to 112l, internal conductors 114a to 114f, and via-hole conductors B1 to B5. The magnetic layers 112a to 112l are insulator layers arranged in this order from the upper side in the stacking direction to the lower side. [0004] The inner conductor 114a is provided on the magnetic layer 112d, and one end is drawn out from the side surface on the right side of the laminated body 111. The inner conductors 114b to 114e are respectively surrounded by a length of one turn on the magnetic layers 112e to 112h. The inner ...
